This heyword is not suported by this compiler. BOOST_UBLAS_CPP_GE_2011 macro is used to enable/disable the whole class (wrongly on msvc-12.0) instead of enabling only some parts of the code as it's done in other libraries. Another thing is that fixed_vector<> is only available on some compilers which allows the users to write non-portable code. Variadic templates may be emulated with Boost.Preprocessor, e.g. see how emplace_back() is implemented in boost::container::vector<> : https://github.com/boostorg/container/blob/develop/include/boost/container/vector.hpp lines 1309-1380. constexpr may be conditionally used e.g. by one of macros defined in Boost.Config: http://www.boost.org/doc/libs/1_55_0/libs/config/doc/html/boost_config/boost_macro_reference.html#boost_config.boost_macro_reference.macros_that_allow_use_of_c__11_features_with_c__03_compilers" Bugs new To Be Determined uBLAS Boost Development Trunk Problem
